A 32-year-old man accused of raping a 19-year-old woman after she left a night club in Northwest Portland last summer pleaded no contest Monday to second-degree sexual abuse and attempted kidnapping as part of a plea deal which will net him two years in prison, plus time off for good behavior.

Prosecutor Don Rees declined to say why he agreed to settle the case.

Juan Juarez-Paulin was originally charged with first-degree rape which carries a mandatory minimum sentence of 8 1/3 years in prison

MCSOJuan Juarez-Paulin.

The victim told police last summer that she'd been raped by a man who followed her when she left the Roseland nightclub, 8 N.W. Sixth Ave. on June 20. Investigators say DNA collected during an exam of the woman matched Juarez-Paulin's. He said the sex was consensual.

The rape was one of four sexual assaults reported in downtown and Northwest Portland in the summers of 2008 and 2009. The series of sexual assaults prompted one landlord to post a notice in August 2009 warning tenants to be careful. After that notice went up, police put out the first news release on the attacks.

The unsolved cases include a 23-year-old woman who reported she'd been raped after leaving the City Sports Bar on Southwest Fourth Avenue. DNA collected from her matched Juarez-Paulin's, but he said the sex was consensual, and the police said the victim didn't show up for interviews.

The two other reports of attacks were from a 25-year-old woman, who said a man pushed her to the ground and ripped off her underpants after she left the Marathon Taverna on West Burnside, and a 23-year-old woman, who said she was attacked after leaving The Gypsy bar on Northwest 21st Avenue.

Rees and defense attorney Russ Barnett worked out the plea agreement for Juarez Paulin which was approved by Multnomah County Circuit Court Judge Alicia Fuchs. He will be eligible for 20 percent off his two-year term for good behavior.

The judge also sentenced him to five years of probation, and he will be required to register as a sex offender -- if he stays in the United States. Immigration officials have flagged his case for a hearing, which could mean he faces deportation.
